CDs — who needs 'em?

Got all your tunes on an iPod®, iPhone®, or another player? JVC designed the KD-X40 digital media receiver to get the most out of your digital music collection. It doesn't play CDs, but in your car, it doesn't need to.

Do more with your USB connection

JVC upped the power in their USB port, which lets you keep a smartphone charged while it's performing many battery-draining tasks at once. And with your smartphone connected, you can listen to your phone's internal memory as one source and access the little microSD card as another.

Of course, you can still play your iPod like before. Just connect your player to a USB slot and you're good to go. You can dive into your music library using the KD-X40's controls, and enjoy better sound quality than you get with an auxiliary input connection. With your iPhone connected, you can also stream PANDORA® Internet Radio through a free iPhone app.

Separated Variable Color display

The KD-X40 features a super cool display that lets you change the colors on the controls independent from those on the screen — with over 30,000 possible shades per side. You can match your receiver to your dash, support your favorite team, or just make a statement.

Expansion possibilities

It's always good to keep your options open, and this JVC is ready when you want to expand your system. You can talk hands-free on your compatible phone with the help of JVC's Bluetooth® adapter (not included). You'll find that the two sets of preamp outputs make it easier to add and control amps and subs, plus you can switch one set over to subwoofer mode and adjust your bass on the fly. You'll also get two auxiliary inputs for hooking up more gear, like a Dock & Play satellite radio.

Want to keep your steering wheel controls?

In most vehicles, you can use an adapter to connect your vehicle's steering wheel controls to this JVC stereo. Connect a few wires, then program the adapter for your particular car and the JVC, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.

iPod note:

If you're going to use your iPod with this receiver, be sure to check "Details" for specific iPod model compatibility with this receiver or its optional iPod adapter.

Other features and specs:

Why replace your factory radio?

Two good reasons - sound quality and cool features. A new car stereo offers power that's superior to most factory radios, along with more sophisticated tone controls. And most car stereos offer built-in or optional features that add safety and fun to life in your car, including inputs for your iPod or MP3 player, Bluetooth connectivity for hands-free cell phone calls, satellite radio or HD Radio reception, and connections for building an audio system in your car.

Note: Apple iPod/iPhone software updates may change
functionality results. If you download a newer software version, you may
need to reset the head unit and your iPod/iPhone to regain functionality. If
this doesn't work, you may need to wait until a newer software update is
available.

Dual Auxiliary Inputs

Dual Auxiliary Inputs: A front-panel & rear-panel stereo minijack
are provided to allow the connection of portable
audio sources. Simply connect your portable digital music player to either
the unit's front or rear auxiliary input, and you can listen to the audio from the portable player through the
speakers in your mobile audio system.

Simultaneous Connection: The front-panel & rear-panel auxiliary
connections are separate (independent) inputs, so you can connect two portable
audio devices at once to the JVC head unit and select between sources. You can turn the front- and rear-panel auxiliary inputs On
or Off.

Optional Bluetooth

Optional Bluetooth: The
unit's rear-panel auxiliary input can also be used to connect JVC's KS-BTA100
Bluetooth Adapter (105KSBTA10, sold separately).
The KS-BTA100 must be plugged into the rear-panel auxiliary input, and not
the front-panel auxiliary input. The front-panel auxiliary input does not
support Bluetooth. The KS-BTA100 gives
you hands-free communication from your compatible Bluetooth mobile phone and
wireless streaming audio from a Bluetooth enabled digital audio player. The
optional JVC Bluetooth Adapter includes a super-sensitive microphone, an
Answer/End button, and playback controls. The KD-X40 can be set to
automatically mute any music audio to your vehicle's speakers so you can listen
to your telephone call using your car speakers.

Audio Section

MOSFET Amplifier: The KD-X40 is equipped with a MOSFET
amplifier. Compared to conventional power supplies, the MOSFET amplification
circuit is smaller and more efficient, and it delivers increased power with less
distortion and absolutely zero on/off switching noise. More power means louder
and cleaner music at higher volumes because you're not pushing the limits of the
amplification circuit.

CEA2006 Compliant: The power specifications for the KD-X40
are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement
standards from the Consumer Electronics Association (CEA). These standards were
developed as a way to equitably compare power specs from model to model and
between manufacturers. The power output specs for the KD-X40 are as follows:

Amplifier Gain Control: When you
are using the KD-X40 with factory speakers (or those rated to less than 50
watts peak), the Amplifier Gain Control can limit the amount of power being sent
to those speakers. When the Amp Gain Control is set to "low," the volume control
ranges from 0 (minimum) to 30 (maximum). When using speakers rated higher than
50 watts peak, you can set the Amp Gain Control to "high," and the volume
control will range from 0 to 50.

Volume Adjust: The input level of each source (other than FM) is
adjustable relative to the FM radio volume, so there isn't a significant volume
difference when changing sources. Each source is individually adjustable from -5
to +5.

Loud (Loudness): This feature boosts low and high frequencies to produce a well-balanced sound at a low volume
level. You can turn this feature on or off.

2.5V/4CH Preamp Output: The KD-X40
is equipped with two pair of 2.5V preamp outputs (Front, Rear/SW). You can set the Rear/SW preamp outputs for connecting
a pair of full-range rear speakers (through an external amplifier) or for connecting a subwoofer (through an external
amplifier). When set for rear speakers, the rear outputs operate with the unit's
fader control. When set for subwoofer, the outputs are non-fading.

Subwoofer Controls: When the unit's Rear/SW preamp output is set to
Subwoofer, you can adjust the head unit's subwoofer level between 0 to 8
(separate from the main volume level). You can also adjust the low-pass filter
and activate a high-pass filter.

Low-Pass Filter: When the unit's Rear/SW preamp output is set to
Subwoofer, you can
set the cutoff frequency of the low-pass filter at 55Hz, 85Hz, or 120Hz.

High-Pass Filter: When the unit's Rear/SW preamp output
is set to Subwoofer, you can also activate a high-pass filter (fixed at
low-pass filter frequency) for
the unit's front & rear channels (speaker- or preamp-level), so low frequency signals are cut
off from your system's front & rear speakers.

Key-Touch Tone: The in-dash head unit provides an audible
beep to confirm button operation. This function can be turned On or Off.

Display Features

Variable Color LCD & Key Illumination: The JVC KD-X40
features 29 color presets for the LCD and button illumination. You can choose
one of these color presets or select the ColorFlow mode which scrolls through
all 29 color presets. Additionally, there is a User preset, allowing you to
individually adjust the intensity of Red, Green, and Blue from 0 to 31;
resulting in approximately 30,000 custom color options. The chosen color preset
or custom color can be applied to the display panel and the backlighting for all
the buttons.
You can choose to use the same color for the LCD display and button
illumination, or use a separate color for each one. You can also select a
different color for daytime and nighttime in regards to the unit's LCD and
button illumination.

Brightness: The unit offers an adjustable display and button
illumination brightness level (0-31) for day and nighttime driving.

Display/Button Illumination Dimmer: The display/button
illumination dimmer can be set to Off (normal brightness at all times), On
(display/button illumination is always dimmed), or Auto (display dims when
12-volts is applied to the orange/white illumination lead).

Mounting Angle: For proper operation, you must install the
unit within 30-degrees of horizontal.

Remote Control

Wireless Remote Control: The
KD-X40 comes supplied with a wireless remote control (RM-RK52). The remote
contains Attenuator, Sound, Source, Tracking, and Volume functions. The
remote operates off of a single CR2025 3V Lithium-cell battery (included).

Steering Wheel Remote Compatibility: The head unit features
an OEM steering wheel remote control input wire (blue/yellow) within the
included wiring harness that lets you keep your vehicle's factory radio steering
wheel remote controls when used with an optional
steering wheel audio control adapter (sold separately). Please consult
Crutchfield's
Outfit My Car to see if your vehicle is compatible.

does the job

I put one in my 2000 Ranger. Came back to Crutchfield to get one for my 2001 just to find out that it's discontinued and out of stock. I used it with my iPod, until the iPod died. Still have the USB as a source though. The iPod navigation controls were a little time consuming, which is bad while driving. The worst thing about it is the crap adapter unit to mount it in the dash, but that's not the unit.

Excelent head unit. nothing wrong yet!

Well to start off the people that got mad because it was to complex for them or the lights where to flashy apparently has never owned a JVC before. This is a unit that is hard to get used to but after you get past that its amazing! i cant imagine screwing with a USB stick. Id much rather stick to an ancient ipod since it still works. But with this head unit i noticed that it is much like my other JVC head unit which i absolutely love!

Pros:It has many many features and sounds pretty good for such a cheap head unit

sounds good

Replaced an old Clarion deck in my off road truck. Thing I like about it is, one its inexpensive for what you get, second, I like there is no CD player. Who uses CD's anymore, and this is an off road truck, I dont want the cd skipping every time I hit something on the trail.

Pros:Sound great matched with after market speakers, even made stock speakers sound better. There is no faceplate. sounds like it should be a con right? I say no, for one who takes their faceplate off after the first few weeks, the other reason I say its a pro: when off-roading, the one on my Clarion would vibrate its way open and eventually it broke off. It would fall off unless I was on smooth pavement.

Cons:The capacity of the thumb drive you can use could be higher. The remote is tiny, i can see losing it easy. Its about the size of your key fob. but not practical to use on a key ring. Another line on the display would be nice too.

Affordable, but disappointing iPhone integration

Bought this as a replacement to my factory radio after my last iphone adapter broke. The display is OK, although the interface leaves something to be desired. The menu options aren't very intuitive, nor is the ability to switch between various sources. The look is fine, and it's nice to be able to change the color scheme to match my car, both for day and night views.

My biggest gripe is the iphone integration. It's extremely disappointing. When you plug in your iPhone, it immediately starts playing the first song (alphabetically) on your device. Even if you were listening to something else recently (or listening to music from another app), it instantly starts playing when you plug it in. I contacted JVC and they say there's no way to change this, so you're stuck with the stereo blasting out whatever is at the top of your itunes. Really a shame.

JVC KD-X40

Just what I wanted, No CD, No tape, just a radios, a USB and a front and back auxillary ports (there is more in the back). The sound is good, the signals are strong, much better than the factory unit. Just what I was looking for and at a good price. The special came with the installation kit at no extra cost. This unit was not listed as a fit for my car as it did not meet the clearance criteria of the Crutchfield engineers, An advisor suggested it when I said that the fit units were above my price points or were not getting good ratings, This lengthened my search.

works with some setup

I bought a 32gb usb stick to use with this unit. The unit can only see 255 songs in a directory, so I had to create about 25 subdirectories on my usb stick and divide my library between them all. That was a bit of a chore.

Pros:Works great w/ my Ipod.

Cons:Needed to use an interface box to make it work w/ my steering wheel controls

Was purchased to replace an aging eight year old Pioneer unit.

When using a thumb drive the folder up down buttons work in reverse - pressing the down arrow button goes up in the folder tree, while pressing the up arrow button goes down in the folder tree. A reset of the unit did not change this behavior.

Scroll feature - when placed in Scroll Auto mode - the ID3 tags are supposed to scroll every five seconds - well they do and they don't. They will scroll if you have the Display set to show a tag, but if you have the display to show either the clock or the elasped time of the track - it only scrolls once and then goes to the time display.

ID3 Tags - It only shows the Album, Artist and song title, no other tags. I would have liked it to have a menu and allow me to pick and choose what tags to display along with file and folder names as well. The old Pioneer showed more.

Since it is a digital media player I would have thought it should behave like most personal MP3 players when using a thumb drive. But it doesn't.

Will not allow you to pick a genre, playlist, artist, albums, or songs. Yes you can scroll through the folders on the thumb drive - attempting to find what you want - but if you are using a 16gig thumb drive it will take some time. Though you really should be watching the road.

Only supports WMA and MP3 formats on the thumb drive. If you like WAV, FLAC or OGG format - sorry they won't play.

(continued in pros and cons)

Pros:I understand it takes time to build the database (my mp3 players anyway) and that may be why JVC chose not to have this unit behave like an mp3 player. Though they could have set the unit to begin playing a song from the thumb drive while the database was being created.
If you only intend to use it with your mp3 player then it will probably be OK for you. Otherwise pay closer attention to what the manual has to say.

Awesome Unit!!

This unit was just what i was looking for. I needed a stereo that would play my Ipod and charge it at the same time and I found it. I have been using it for about 3 weeks now and no problems. If you are looking for an inexpensive upgrade to your factory stereo this is the one, it works great and installed easy. I installed it into my F-150 in about 45 minutes and my next upgrade will be my door speakers, cant wait for that. Thank you Crutchfield for throwing in the mounting kit and wiring harness.

JVC KD-X40 is a great product!

The JVC KD-X40 is an all-in-one media center with everything you need to keep the party moving down the road. The usb feature alone was the factor that sold me on this unit but when I discovered that it had rca outputs, sound EQ, ipod display and controls, and a light price tag I just knew that this unit was the one for me. Look no further....Buy the JVC KD-X40. You will not be disappointed.

OK...should have spent $20 more

For the price its not too bad but you get what you pay for. The EQ isnt very easy to use, you can set a custome preset EQ but you cant just adjust it on the fly...you have to go adjust your custom preset EQ or use one of the build in EQ settings like "Base", "vocal" "flat" etc.. You also cant adjust the speaker output from Left to right or front to back which I need for my kids (in our van). The USB input is good for ipods and iphones but it doesnt work with my Android phone so I need to connect it to the Auxiliary input. If you use Pandora it is ok but you cant thumbs up or thumbs down a song, just skip and pause/play. The install was easy in my 2000 Honda Odyssey, took about 1hr with the install kit from crutchfield. I do wish I spent about $20 or $30 more for a little better deck...this deck is sleek but sacrifices some functionality.

Attnetion Getter

I was so memorized with the variety of custom colors that I did not notice the unit was not CD compatible. But decided to install it regardless ... Looks great and sounds great. Came with everything I needed. My first time installing anything audio, and couldnt have been easier.

Pros:MP3 and Aux compatible. Plenty of color choices to choose from for customization.

great radio

This radio is very good and well worth the money. The radio is a bit long doesn't fit all the way in to car but fits enough. The sound that comes out is amazing a really noticible improvement from my old radio.

Pros:Controls ipod so you don't need to fumble with ur ipod to change a song

When is the last time you bought a CD?

I honestly cant remember the last time I purchased a CD. The deck was a perfect replacement from the factory deck in my Jeep. Easy instalation. A little disappointed in the remote. Doesnt give you full control. I did have to read the owners manual once to figure it all out, but that's why it came with one! Plenty of imputs. Built in high/low pass filter if you add a sub. If only the face detached!!! Then again, if someone steals it, I'm only out this much.

Nice digital media receiver for the money!

Plays all my mp3s on a usb drive. No more cds! Variable colors that can be adjusted for day and night use. I just let the colors change by themselves instead of setting it to one color. It's like having a nightclub in my car lol. Read the manual so you know how to preset the radio stations. You'll be confused if you don't. Other than that I recommend this digital media receiver.
